Ford customers are in for a bit of disappointment, as the automaker is delaying some Mustang Mach-E deliveries for quality reviews.

An electric SUV, the Mach-E is one of the most highly-anticipated vehicles, and is considered to be a real challenger to Tesla’s dominance in the electric vehicle market. The SUV was even named North American Utility Vehicle of the Year at the 2021 North American Car, Truck, and Utility Vehicle of the Year (NACTOY) Awards.

Customers looking forward to getting behind the wheel will need to wait a bit longer, however, as they began receiving emails Thursday evening that their orders would be delayed.

The Detroit Free Press received confirmation from Ford that a few deliveries were already made in December. However, the company confirmed several hundred deliveries would be delayed.

“As part of our commitment to delivering high-quality vehicles, we are conducting additional quality checks on several hundred Mustang Mach-E models built before dealer shipments started last month. We want to ensure they meet the quality our customers expect and deserve,” Ford spokeswoman Emma Bergg told the Free Press.

“We notified affected customers (several hundred in US and Canada) that they may receive their Mustang Mach-Es on different timing than previously discussed,” she continued. “The team is working to expedite these vehicles, and we hope that customers receive them ahead of targeted dates, providing there are no COVID-19-related transportation delays.”

While disappointing for Ford’s customers, the company is obviously concerned with making sure they get this launch perfect. Given what’s at stake, and Ford’s increasingly rivalry with Tesla, it’s understandable that they’re not taking any chances.
